2023-08-24tcg/arm: Implement negsetcond_i32Richard Henderson2-1/+10
Trivial, as we simply need to load a different constant in the conditional move. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2023-08-24tcg/ppc: Use the Set Boolean ExtensionRichard Henderson1-0/+22
The SETBC family of instructions requires exactly two insns for all comparisions, saving 0-3 insns per (neg)setcond. Tested-by: Nicholas Piggin <npiggin@gmail.com> Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-08-24tcg/ppc: Implement negsetcond_*Richard Henderson2-49/+82
In the general case we simply negate. However with isel we may load -1 instead of 1 with no extra effort. Consolidate EQ0 and NE0 logic. Replace the NE0 zero-extension with inversion+negation of EQ0, which is never worse and may eliminate one insn. Provide a special case for -EQ0.

2023-08-24hw/loongarch: Fix ACPI processor id off-by-one errorJiajie Chen1-1/+1
In hw/acpi/aml-build.c:build_pptt() function, the code assumes that the ACPI processor id equals to the cpu index, for example if we have 8 cpus, then the ACPI processor id should be in range 0-7. However, in hw/loongarch/acpi-build.c:build_madt() function we broke the assumption. If we have 8 cpus again, the ACPI processor id in MADT table would be in range 1-8. It violates the following description taken from ACPI spec 6.4 table 5.138: If the processor structure represents an actual processor, this field must match the value of ACPI processor ID field in the processor’s entry in the MADT. It will break the latest Linux 6.5-rc6 with the following error message: ACPI PPTT: PPTT table found, but unable to locate core 7 (8) Invalid BIOS PPTT Here 7 is the last cpu index, 8 is the ACPI processor id learned from MADT. With this patch, Linux can properly detect SMT threads when "-smp 8,sockets=1,cores=4,threads=2" is passed: Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 2 The detection of number of sockets is still wrong, but that is out of scope of the commit.
